JON HAMM
AGE 37
HE PLAYS Don Draper, ad firm partner and man with a past.
RESUME Starred in the 2002 indie hit Kissing Jessica Stein with girlfriend Jennifer Westfeldt.
HAS FAME CHANGED HIM? "Not much," says the Missouri-born Emmy nominee. "I have breakfast with my dog and read the paper." His attire helps. "I don't, in my real-life dress, look too much like Don. When my hair is not slicked back and I'm not buttoned into very tight-fitting suits, I'm able to blend into the background."
JANUARY JONES

RESUME Played Matthew Fox's wife in 2006's We Are Marshall.
BEST JOB BENEFIT "Women were a little softer and more voluptuous back then," says Jones of Mad Men's 1960s setting. "I don't work out at all, and I have an excuse why I can't. I gain a couple of pounds and [the producers] love it."

ELISABETH MOSS

VINCENT KARTHEISER
AGE 29
HE PLAYS Pete Campbell, weaselly account executive.

GOT A LIGHT? Why is Pete one of the only nonsmokers? "He comes from a family with money," says the Minnesota native. "It wasn't polite." But he wouldn't be opposed to taking a drag: "Actors love props. They love to have something to light, pocket and pinch."
